Mom was going to Europe and she gets on the plane and she's standing in the doorway waiting for people in front of her with her hands on the top of the doorway and she says completely oblivious to what the words coming out of her mouth are going to sound like: "I feel like I could hold up the whole plane from here"

Everyone turns and looks at her, the look of utter shock and horror on her face is enough that everyone immediately finds it hilarious except her. Priceless.
